Belon oysters are a unique type of flat oyster native to the Belon River in France. Known for their distinctive, slightly metallic taste, they are often considered a delicacy among seafood lovers. These oysters have a round shape and a smooth shell, typically measuring around 3 to 4 inches in diameter. Harvested primarily from the Brittany region, Belon oysters thrive in the brackish waters where fresh and saltwater mix. They are usually enjoyed raw on the half shell, often accompanied by lemon or mignonette sauce. Their flavor profile is influenced by the specific environment in which they are grown.
